Just a quick query based on my internet in the Roman "cultural commonwealth" of the Macedonian and Komnenian periods (10th thru 12th centuries). I know that the early Arpad Kingdom of Hungary was between the centers of Orthodoxy (ERE/Kiev Rus) and the centers of "Latin" Christendom (Italy/Germany) during this period and the Constantinople's diplomatic, economic and political connections to the Arpads were often quite intense. If the Komnenoi are more successful in absorbing parts of Hungary after the Battle of Sirmium in 1167, for example, could that region and Transylvania become part of the Orthodox world and perhaps an integral part of the Eastern Empire? The idea of an Orthodox Hungary and of a successful Constantinople that expands north and west as the OTL Ottomans did in time intrigues me..thanks for any responses!
